Q: 4. Lens cover for this lens? I have a Tiffen 82 mm but it does not attach to this lens! Recommended lens cover is not shown in Accessories. What lens cover will work for the WCX-80??

A: I tried 2 Tiffen UV filters and they are very hard to screw on because ether the thread count is different or there aren't enough. When you get it on there is a slight crop in the upper left corner with active steadyshot off. When it's on and you pan quickly, the crop is large. There also is a reflection going on from the filter to the adapter when light hits it. I rely on the rubber Zunow lens hood for protection because much of the time you can't use the UV filter for these reasons.
